JTAG Master function for embedded debug and testhttp://blog.asset-intertech.com/test_data_out/2017/12/jtag-master-function-for-embedded-debug-and-test.html
In my last article, I described how the Open Compute Project (OCP) Project Olympus server designs have been put into the public domain by Microsoft Azure. Inherent in the Olympus servers is the hardware connection between the ASPEED BMC and the CPU JTAG chain. To make the most of this connection for hardware-assisted debug and test purposes, a high-performance, secure JTAG Master function is needed within the BMC.Boundary ScanEmbedded DiagnosticsIndustry Standards and ForumsSoftware Debug and TraceSoftware Debug and Trace - ARMSoftware Debug and Trace - IntelAlan Sguigna2017-12-10T16:49:53-06:00Microsoft Project Olympus Schematics and Embedded JTAG Run-Controlhttp://blog.asset-intertech.com/test_data_out/2017/12/microsoft-project-olympus-schematics-and-embedded-jtag-run-control.html
As part of the Open Compute Project, Microsoft Azure is leading the charge in providing the technical information needed to democratize the server industry. Recently, they put into the public domain the full schematics and board files for an Intel Xeon Scalable Processor (Skylake-EP) server design. Reviewing the schematics provides great insight into the hardware design implementation needed to support at-scale debug via embedded JTAG run-control.Boundary ScanEmbedded DiagnosticsSoftware Debug and TraceSoftware Debug and Trace - ARMSoftware Debug and Trace - IntelAlan Sguigna2017-12-03T16:26:36-06:00The MinnowBoard Chronicles Episode 28: Returning my AMD Ryzen 7 1700X CPUhttp://blog.asset-intertech.com/test_data_out/2017/11/the-minnowboard-chronicles-episode-28-returning-my-amd-ryzen-7-1700x-cpu.html

Embedded microcontrollers often get ignored in the main stream tools market for production testing and development. Up until recently, these devices had a limited role when compared to a System On-Chip (SoC). Sure the microcontroller market has moved from 16-bit to 32-bit, but still played a simple, often single function...Processor-based Fast Programming (PFP)Larry Osborn2017-11-15T13:57:30-06:00The MinnowBoard Chronicles Episode 27: Segfault on my AMD Ryzen 7 1700Xhttp://blog.asset-intertech.com/test_data_out/2017/10/the-minnowboard-chronicles-episode-27-segfault-on-my-amd-ryzen-7-1700x.html
Last week, I suspected that I might be seeing segmentation fault failures on my new AMD Ryzen 7 1700X computer. I dug into this some more this week, and learned a lot!Boundary ScanSoftware Debug and TraceSoftware Debug and Trace - ARMSoftware Debug and Trace - IntelAlan Sguigna2017-10-29T17:54:32-05:00The MinnowBoard Chronicles Episode 26: Linux image build segmentation faults on AMD?http://blog.asset-intertech.com/test_data_out/2017/10/the-minnowboard-chronicles-episode-26-linux-image-build-segmentation-faults-on-amd.html
It has been quite an adventure over the last week. I’m getting intermittent segmentation faults during my Yocto Linux image builds. Could it be a problem with my new AMD Ryzen 7 1700X CPU?Embedded DiagnosticsSoftware Debug and TraceSoftware Debug and Trace - ARMSoftware Debug and Trace - IntelAlan Sguigna2017-10-22T17:21:15-05:00The MinnowBoard Chronicles Episode 25: Yocto builds for the MinnowBoard and the Portwell Neptune Alphahttp://blog.asset-intertech.com/test_data_out/2017/10/the-minnowboard-chronicles-episode-25-yocto-builds-for-the-minnowboard-and-the-portwell-neptune-alph.html
In Episode 24, I finished off my new build machine, successfully did a QEMU image build on it, and loaded an off-the-shelf Ubuntu image into my new MinnowBoard Turbot. This week, I tackled a MinnowBoard Linux image build using Yocto, loaded it into my MinnowBoard, and also set about doing a Yocto image build for the Portwell Neptune Alpha board. But I ran into some problems.Arium Probes | SourcePoint™Embedded DiagnosticsSoftware Debug and TraceSoftware Debug and Trace - ARMSoftware Debug and Trace - IntelAlan Sguigna2017-10-16T07:05:33-05:00The MinnowBoard Chronicles Episode 24: New MinnowBoard, New PC, and a nod to Netgatehttp://blog.asset-intertech.com/test_data_out/2017/10/the-minnowboard-chronicles-episode-24-new-minnowboard-new-pc-and-a-nod-to-netgate.html
In Episode 23, I mentioned taking a short sabbatical, because my MinnowBoard USB ports stopped working, and my 7-year-old home PC build machine crashed. The good news is both of these issues are both fixed!
